MARINE GOVERNOR.

Specification of Letters Patent.

Patented Sept. 21, 1915.

Application filed February 20, 1915. Serial No. 8,632.

b all whom it may concern Be it known that 1, Noitn DUPUIS, a citizen of the United States, residing at Aberdeen, in the county of Chehalis and State of Washington, have invented a new and useful Marine Governor, of which the following is a specification.

The present invention appertains to a marine governor, and aims to provide a novel and improved device for automatically shutting off the supply of steam to the engine when the propeller is lifted partially or completely out of the water, and for automatically reestablishing' the supply of steam to the engine as soon as normal conditions are resumed or when the propeller is again submerged sufliciently below the surface of the water.

It is also within the scope of the invention to provide a marine governor of the nature indicated, for preventing the speeding of the engine due to the lifting of the propeller partially or completely out of the water, and which is comparatively simple and inexpensive in construction as well as being efiicient and practical innse.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in its preferred embodiment in the accompanying drawing, wherein:-

Figure l is a plan View of the improved governor. Fig. 2 is a longitudinal vertical section thereof, parts being shown in full.

1n carrying out the invention there is employed a rocking channel or trough 1, which is fulcrumed intermediate its ends. To this end, a transverse rock shaft 2 is secured to the bottom of the channel or teeter 1 and the end portions of the shaft 2 project laterally beyond the sides of the trough or channel 1, to provide trunnions which are seated in slots or seats 3 provided in the upper ends of a pair of suitable standards 4 carried by the ship provided with the present apparatus. The channel or trough 1 is preferably disposed longitudinally over the steam supply pipe 5 leading to the engine (not shown), and the pipe 5 is provided with a throttle or controlling valve 6 beyond one end of the trough 1. The valve 6 is provided with a radial operating arm 7, and the valve 6 is normally open to admit steam to the engine.

The trough 1 is operatively connected to the valve 6, and to this end an arm 8 is secured rigidly to one end of the trough 1 and projects longitudinally from the said end of the trough away from the fulcrum or pivot of the trough, whereby a suitable leverage is accomplished for actuating the valve 6. The free ends of the arms 7 and 8 are connected by a link 9, whereby when the said end of the trough 1 having the arm8 is raised, the valve 6 will be held open, and when the said end of the trough is lowered, it will swing the valve arm 7 downwardly to close the valve 6.

A ball or equivalent weight 10 is disposed within the trough 1 for longitudinal move ment therein, and i's'normally disposed at that end of the trough 1 remote from the valve, to thereby depress the last mentioned end of the trough, and hold the other end of the trough up to hold the valve 6 open.

In order to firmly support that end of the trough I normally holding the ball or weight 10, as seen in the drawing, and for normally holding the trough 1 at the slight angle as seen in Fig. 2, a transverse rod 11 is secured to the bottom of the trough 1 adjacent that end of the trough in which the ball 10 is normally disposed, the end portions of the rod 11 project laterally and normally seat within upper open slots or seats 12 provided in the upper ends of a pair of standards 13 attached to a suitable supporting member of the ship. The rod 11 of the trough being seated upon the standards 13 will normally support the trough in proper position.

In order to hold the ball 10 at the end of the trough 1 in which it is normally arranged, a bail 1 1 is terminally pivoted or journaled to a cross rod 15 secured upon the upper edges of the sides of the trough 1 between the ends of the trough, and the bail 14 normally rests upon another cross rod 16 secured upon the upper edges of the sides of the trough 1 at that end of the trough 1 adjacent the valve 6. The bail 14. can be swung into the trough 1 for holding the ball 10 at the end of the trough in which it is illustrated in the drawing, and. which will prevent the ball 10'from rolling to the 0pposite end of the trough for swinging or tilting the same to close the valve 6.

In operation, that end of the trough l which normally holds the ball 10 is disposed aft or projects toward the stern of the boat, while-the otherend of thetrough 1 which is normally raised is disposed toward the.

' tially' or completely lift the propeller out of the water, the trough 1 will be inclined toward the stern, and this will cause the ball or weight 10 to roll to the fore end of the trough 1, which will cause the fore end of the trough to be depressed, and this will close the valve 6. As a result, the steam will be shut off, and the engine will be stopped during the time that the propeller is raised out of the water, and this will prevent the speedingofthe engine which is so injurious to the entire ship. When the ship assumes a normal position, the trough 1 will be brought to a forwardly inclined position,

and the ball or weight 10 will roll back to the aft end of the trough 1 to again open the valve 6 and to allow the engine to operate.

. The present contrivance thus operates automatically to shut off and reestablish the flowof steam to the engine when the propeller is lifted out of the water and again submerged, respectively. The present device may be rendered inoperativeby swinging the bail 14 into the trough l to prevent the ball or weight 10 from rolling back and forth between the ends of the trough. The present device may be applied to any desirable part of the boat, and instead of employing the ball or weight 10, quick silver or an equivalent medium may be employed in the trough 1 for tilting or rocking the trough under the various conditions. trough 1 may be closed, if desired, especially when quick silver or a mobile weight is employed.

Having thus described the invention, what is claimed as new is A marine governorcomprising a trough fulcrumed intermediate its ends, a weight The v movable within the trough between the ends thereof, means for operatively connecting the trough with a controlilng valve, and a pivoted member carried by the trough and adapted to be swung into the same for holding the weight adjacent one end of the trough.

In testimony that I claimthe foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
